Workers from a range of sectors in Israel launched a nationwide strike on Monday, threatening to paralyze the economy as they joined a surging protest movement against Prime Minister Benjamin Netanyahu’s plan to overhaul the judiciary.

Departing flights from the country’s main international airport were grounded, large mall chains and universities shut their doors, and Israel’s largest trade union group called for its 800,000 members — in health, transit, banking and other fields — to stop work. Local governments were expected to close the preschools they run and cut other services, and the main doctors union announced its members would also walk off the job.

The growing resistance to Netanyahu’s plan came hours after tens of thousands of people burst into the streets around the country in a spontaneous show of anger at the prime minister’s decision to fire his defense minister after he called for a pause to the overhaul. Chanting “the country is on fire,” they lit bonfires on Tel Aviv’s main highway, closing the thoroughfare and many others throughout the country for hours.

Thousands of protesters gathered Monday outside the Knesset, or parliament, to keep up the pressure.
